| ### Breaking changes |
| |
| This major release introduces **three breaking changes** that may require updates from consumers of `@mdn/browser-compat-data`. |
| |
| #### 1. Removal of `null` and `true` version values ([#24174](https://github.com/mdn/browser-compat-data/pull/24174)) |
| |
| Previously, the `version_added`, `version_removed` and `version_last` fields allowed `null` (indicating support is unknown) and `true` (indicating support added/removed in an unknown version). |
| |
| Now, these values have been **removed from the schema**. All existing instances have been replaced with explicit or ranged version numbers (e.g. “≤37“). |
| |
| **Impact**: Consumers handling `null` or `true` values may need to update their code. |
| |
| #### 2. Improved TypeScript definitions for array values ([#26172](https://github.com/mdn/browser-compat-data/pull/26172)) |
| |
| Several fields, such as `notes`, accept either a single value or an array of at least two values. |
| |
| Previously, TypeScript definitions used `string | string[]`, requiring consumers to validate array values manually. |
| |
| Now, these types are more precisely defined as `string | [string, string, ...string[]]`, ensuring that **arrays contain at least two values** when used. |
| |
| **Impact**: Consumers validating array values may need to update their code. |
| |
| #### 3. New top-level `manifests` folder ([#26109](http://github.com/mdn/browser-compat-data/pull/26109)) |
| |
| Previously, support data for the Web Application Manifest was placed under `html/manifest`, which inaccurately implied it was an HTML subfeature. |
| |
| Now, a new top-level `manifests` folder has been created to host the Web Application Manifest under `manifests/webapp` to better reflect its independence, and to support future manifest types like the Payment Method Manifest. |
| |
| **Impact**: Consumers referencing Web Application Manifest data may need to update their code. |
| |
| ### Renamings |
| |
| - `html.manifest.*` to `manifest.webapp.*` ([#26109](https://github.com/mdn/browser-compat-data/pull/26109)) |
